United States Fish and Wildlife Service

The United States Fish and Wildlife Service (USFWS) or (FWS) is an agency of federal government within the U.S. Department of the Interior which is dedicated to the management of fish, wildlife, and natural habitats. The mission of the agency is "working with others to conserve, protect, and enhance fish, wildlife, plants and their habitats for the continuing benefit of the American people."

The leader of the FWS is the director of the U.S. Fish and Wildlife Service Daniel M. Ashe, of Maryland, who was confirmed on June 30, 2011, succeeding Sam Hamilton.

Among the responsibilities of the FWS are enforcing federal wildlife laws, protecting endangered species, managing migratory birds, restoring nationally significant fisheries, conserving and restoring wildlife habitat, such as wetlands, helping foreign governments with their international conservation efforts, and distributing money to states' fish and wildlife agencies through the Wildlife Sport Fish and Restoration program.
